• transforming binary data using ssis and sql server 2008

  - by Rick

  Hello All - I have a task to import/transform and extract zipped binary files that contain both text data as well as embeded binary data. Within the data is data that is relational in nature and needs to be processed into a defined database structure. Currently I have a C# single threaded app that essentially grabs all the files from the directory (currently there is 13K files of varying sizes) and extracts the data on a single thread line by line inserts to the database. As you could imagine this is a very slow process and unacceptable. There are several different parsing routines used depending on the header record in the file. There are potentially upto a million rows per file when all the data is extracted to the row level of detail. Follow on task is to parse those rows into their appropriate tables based on is content. i.e. the textual content has to be parsed further into "buckets" of like data in the database. That about sums up the big picture. Now for the problem task list. How do i iterate through a packet of data using SSIS? In the app the file is decompressed and then is parsed using streams data type and byte arrays and is routed to the required parsing routine based on the header data of each packet. There is bit swapping involved as well. Should i wrap up the app code into a script task(s) and let it do the custom processing? The data is seperated by year and the sql server tables is partitioned by year as well. I need to be able to "catch" bad file data as well and process by hand most likely. Should i simply load the zipped file to sql as a blob and parse the file with T-SQL? Would that be multi threaded if done that way? Not sure how to do the parsing in tsql that is involved here. Which do you think would be faster? Potentially the data that is currently processed via files could come to us via a socket. Can SSIS collect that data in real time? How would i go about setting that up? Processing these new files from the directorys will become a daily task. I can manage the data once i get it to sql server. Getting it there in a timely fashion seems to be the long pole in the tent for me. I would appreciate any comments or suggestions from the group. Rick

• XML parsing error: 'A string literal was expected' when inserting values into table

  - by Christian

  In Microsoft Sequel Server 2008 I am attempting to insert values into an sql table with the columns type_id of datatype int and xml_info of datatype XML. I am using the following query: INSERT INTO tbl_applied_devices ([type_id],[xml_info]) VALUES (1,'<Profile ID=99><Server><ID>BC4A18CA-AFB5-4268-BDA9-C990DAFE7783</ID> <Name>localhost</Name><Services></Services></Server></Profile>') But I keep getting this error: Msg 9413, Level 16, State 1, Line 4 XML parsing: line 1, character 13, A string literal was expected What am I doing incorrectly? Thank you for the help. EDIT: I found that the source of the error is the xml element's ID attribute, where seems to be what is causing the error. How can I correctly insert xml with an attribute ? Do I need to somehow escape one of the characters?

• T-SQL: Compute Subtotals For A Range Of Rows

  - by John Dibling

  MSSQL 2008. I am trying to construct a SQL statement which returns the total of column B for all rows where column A is between 2 known ranges. The range is a sliding window, and should be recomputed as it might be using a loop. Here is an example of what I'm trying to do, much simplified from my actual problem. Suppose I have this data: table: Test Year Sales ----------- ----------- 2000 200 2001 200 2002 200 2003 200 2004 200 2005 200 2006 200 2007 200 2008 200 2009 200 2010 200 2011 200 2012 200 2013 200 2014 200 2015 200 2016 200 2017 200 2018 200 2019 200 I want to construct a query which returns 1 row for every decade in the above table, like this: Desired Results: DecadeEnd TotalSales --------- ---------- 2009 2000 2010 2000 Where the first row is all the sales for the years 2000-2009, the second for years 2010-2019. The DecadeEnd is a sliding window that moves forward by a set ammount for each row in the result set. To illustrate, here is one way I can accomplish this using a loop: declare @startYear int set @startYear = (select top(1) [Year] from Test order by [Year] asc) declare @endYear int set @endYear = (select top(1) [Year] from Test order by [Year] desc) select @startYear, @endYear create table DecadeSummary (DecadeEnd int, TtlSales int) declare @i int -- first decade ends 9 years after the first data point set @i = (@startYear + 9) while @i <= @endYear begin declare @ttlSalesThisDecade int set @ttlSalesThisDecade = (select SUM(Sales) from Test where(Year <= @i and Year >= (@i-9))) insert into DecadeSummary values(@i, @ttlSalesThisDecade) set @i = (@i + 9) end select * from DecadeSummary This returns the data I want: DecadeEnd TtlSales ----------- ----------- 2009 2000 2018 2000 But it is very inefficient. How can I construct such a query?

• How to create SQL Server Express DB from SQL Server DB

  - by jeff

  I have a SQL Server 2008 DB. I want to extract SOME tables (and associated schema, constraints, indexes, etc) and create a SQL Server Express DB. It isn't a sync of the target, we stomp on it. We ONLY need to do this in the file system (not across the wire). We are not fond of the synchronization stuff and at this point don't know how to run SSIS. We are a C# shop and a little code is ok. Like using the C# bulk import stuff, but that won't create the schema. Suggestions?

• TSQL Cascade delete for child records?

  - by ElHaix

  I have a parent/child table (simple tree) table structure (ID, ParentID), where I want to delete (and get the ID of) all children for a given parent ID - similar to this post http://stackoverflow.com/questions/1433808/sql-server-cascade-delete-and-parent-child-table . During the loop, where I've got the current ID, I will also be performing other actions with this ID. Can someone give me an example of the SPROC to accomplish this? Thanks

• How to code Microsoft Excel "Shift Cells Up" feature in SQL

  - by user293249

  Take a simple table like below: Column Headings: || Agent's Name || Time Logged In || Center || Row 1: Andrew || 12:30 PM || Home Base Row 2: Jeff || 7:00 AM || Virtual Base Row 3: Ryan || 6:30 PM || Test Base Now lets say that a single cell is deleted so the table now looks like this: Column Headings: || Agent's Name || Time Logged In || Center || Row 1: Andrew || 12:30 PM || Row 2: Jeff || 7:00 AM || Virtual Base Row 3: Ryan || 6:30 PM || Test Base Notice that "Home Base" is missing. Now in excel you can delete the cell and shift the rest so the finished product looks like below: Column Headings: || Agent's Name || Time Logged In || Center || Row 1: Andrew || 12:30 PM || Virtual Base Row 2: Jeff || 7:00 AM || Test Base Row 3: Ryan || 6:30 PM || And you can see we are left with a blank cell last row. How do I code this procedure of shifting the cells up in SQL? I've been struggling on this problem for weeks! Thank you!

• How to use SMO.Scripter to generate a "full-script" of DB?

  - by ssg

  What I'm trying to do is a very simple task; I'd like to create a script to generate a database along with tables, SPs and UDFs. This is done with a couple of clicks on SSMS interface. However db.Script() only scripts CREATE DATABASE. Ok, so I iterate over objects one by one and script them individually. Now, what I have is an arbitrary order of CREATEs naturally failing during execution because dependent objects aren't created first. Ok so I set WithDependencies flag so dependent objects ARE scripted first. However this causes redundant CREATE scripts for objects that are already created, and causes around 20x growth in SQL file and generation time. Not to mention the errors hit during execution. I don't know if there is a way to mark objects "already walked in dependency tree", it doesn't seem likely. I might be missing a bigger picture somewhere, but MSDN recommends "Scripter" to generate scripts like the one I want. I had used Transfer class before to transfer table definitions but it fails to create a failsafe script. It doesn't make sense to use a Transfer object to generate a script anyway. I want to do this the way it should be done, and without losing my faith in SMO.

• "If not exists" fails on SQL CE

  - by Mark Evans

  Hi I've got an unexpected problem. I'm making a script to update the schema on a SQL CE database. This won't run: if not exists ( Select column_name from information_schema.columns where column_name = 'TempTestField' and table_name = 'Inventory_Master_File' ) Alter table Inventory_Master_File add TempTestField nvarchar(10) null I think this is because I'm using stuff that isn't supported in SQL CE. Anyone know how to do this? I've tried rearranging the script and can't get anything to work. I tried "alter table ... where not exists ...". Note that the "select" part runs fine and also the "alter" part. The problem is "if not exists". I know there are some other postings regarding problems like this using SQL CE but I couldn't find an answer to this particular problem. Cheers Mark UPDATE: I've spent over an hour looking for a solution. I've found many postings asking for help with similar problems but I've still got no idea how to fix it. I really don't want to do this in C# code. I need to do this in a SQL script. I can't believe something this basic is causing so much difficulty :(

• Faster way to transfer table data from linked server

  - by spender

  After much fiddling, I've managed to install the right ODBC driver and have successfully created a linked server on SQL Server 2008, by which I can access my PostgreSQL db from SQL server. I'm copying all of the data from some of the tables in the PgSQL DB into SQL Server using merge statements that take the following form: with mbRemote as ( select * from openquery(someLinkedDb,'select * from someTable') ) merge into someTable mbLocal using mbRemote on mbLocal.id=mbRemote.id when matched /*edit*/ /*clause below really speeds things up when many rows are unchanged*/ /*can you think of anything else?*/ and not (mbLocal.field1=mbRemote.field1 and mbLocal.field2=mbRemote.field2 and mbLocal.field3=mbRemote.field3 and mbLocal.field4=mbRemote.field4) /*end edit*/ then update set mbLocal.field1=mbRemote.field1, mbLocal.field2=mbRemote.field2, mbLocal.field3=mbRemote.field3, mbLocal.field4=mbRemote.field4 when not matched then insert ( id, field1, field2, field3, field4 ) values ( mbRemote.id, mbRemote.field1, mbRemote.field2, mbRemote.field3, mbRemote.field4 ) WHEN NOT MATCHED BY SOURCE then delete; After this statement completes, the local (SQL Server) copy is fully in sync with the remote (PgSQL server). A few questions about this approach: is it sane? it strikes me that an update will be run over all fields in local rows that haven't necessarily changed. The only prerequisite is that the local and remote id field match. Is there a more fine grained approach/a way of constraining the merge statment to only update rows that have actually changed?

• Generating the query plan takes 5 minutes, the query itself runs in milliseconds. What's up?

  - by TheImirOfGroofunkistan

  I have a fairly complex (or ugly depending on how you look at it) stored procedure running on SQL Server 2008. It bases a lot of the logic on a view that has a pk table and a fk table. The fk table is left joined to the pk table slightly more than 30 times (the fk table has a poor design - it uses name value pairs that I need to flatten out. Unfortunately, it's 3rd party and I cannot change it). Anyway, it had been running fine for weeks until I periodically noticed a run that would take 3-5 minutes. It turns out that this is the time it takes to generate the query plan. Once the query plan exists and is cached, the stored procedure itself runs very efficiently. Things run smoothly until there is a reason to regenerate and cache the query plan again. Has anyone seen this? Why does it take so long to generate the plan? Are there ways to make it come up with a plan faster?

• Concatenating Date Values - SQL Injection

  - by Kyle Rozendo

  Hi All, We currently receive parameters of values as VARCHAR's, and then build a date from them. I am wanting to confirm that the method would stop the possibility of SQL injection from this statement: select CONVERT(datetime, '2010' + '-' + '02' + '-' + '21' + ' ' + '15:11:38.990') Another note is that the actual parameters being passed through to the stored proc are length bound at (4, 2, 2, 10, 12) in correspondence to the above. Thanks a ton, Kyle

• SSIS package randomly hangs during execution

  - by Adam MacLeod

  Hi Guys, I am having an ongoing and painful problem with an SSIS package. The package runs every 5 minutes as an SQL Agent Job and every 2-10 days the package will start running and never stop (thus preventing further executions). If I stop the hung job manually it will begin working perfectly again in the next 5 minute interval. The SSIS package is for moving data from an Oracle database to a MSSQL 2005 database. It has 7 steps: Step 1 calls an Oracle Stored Procedure to prepare the temporary tables inside ORACLE Steps 2-6 process the data from the ORACLE tables to the MSSQL tables ORACLE - MSSQL Step 7 calls an Oracle Stored Procedure to clear the ORACLE temporary tables I suspect that the issue is caused by a communications error between the MSSQL server and the ORACLE server. Both the MSSQL database and Agent/package run on one machine with the ORACLE database running over the network. I have enabled logging of the SQL package and after more than 2GB of log file I have captured the instant where the package stops responding: OnPreValidate,ADV-SRV5,NT AUTHORITY\SYSTEM,CallistaIntegrationToMonashCRM_delta,{F88F6C45-CFA2-4801-A2F2-DDF03D458A48},{3A1FB1E3-B76D-444D-876B-D1FBBB9BA246},6/06/2010 10:15:01 AM,6/06/2010 10:15:01 AM,0,0x,(null) OnPreValidate,ADV-SRV5,NT AUTHORITY\SYSTEM,Address,{c5907799-f918-43da-818a-d4bd7f188367},{3A1FB1E3-B76D-444D-876B-D1FBBB9BA246},6/06/2010 10:15:01 AM,6/06/2010 10:15:01 AM,0,0x,(null) OnInformation,ADV-SRV5,NT AUTHORITY\SYSTEM,Address,{c5907799-f918-43da-818a-d4bd7f188367},{3A1FB1E3-B76D-444D-876B-D1FBBB9BA246},6/06/2010 10:15:01 AM,6/06/2010 10:15:01 AM,1074016266,0x,Validation phase is beginning.

I have not been able to work out a way to either fix this issue or have the package die gracefully (an error to the log would be A-OK with me). Any help or advice would be greatly appreciated.

• SQLCLR and DateTime2

  - by Moe Sisko

  Using SQL Server 2008, Visual Studio 2005, .net 2.0 with SP2 (has support for new SQL Server 2008 data types). I'm trying to write an SQLCLR function that takes a DateTime2 as input and returns another DateTime2. e.g. : using System; using System.Data.SqlTypes; using Microsoft.SqlServer.Server; namespace MyCompany.SQLCLR { public class DateTimeHelpCLR { [SqlFunction(DataAccess = DataAccessKind.None)] public static SqlDateTime UTCToLocalDT(SqlDateTime val) { if (val.IsNull) return SqlDateTime.Null; TimeZone tz = System.TimeZone.CurrentTimeZone; DateTime res = tz.ToLocalTime(val.Value); return new SqlDateTime(res); } } } Now, the above compiles fine. I want these SqlDateTimes to map to SQL Server's DateTime2, so I try to run this T-SQL : CREATE function hubg.f_UTCToLocalDT ( @dt DATETIME2 ) returns DATETIME2 AS EXTERNAL NAME [SQLCLR].[MyCompany.SQLCLR.DateTimeHelpCLR].UTCToLocalDT GO This gives the following error : Msg 6551, Level 16, State 2, Procedure f_UTCToLocalDT, Line 1 CREATE FUNCTION for "f_UTCToLocalDT" failed because T-SQL and CLR types for return value do not match. Using DATETIME (instead of DATETIME2) works fine. But I'd rather use DATETIME2 to support the increased precision. What am I doing something wrong, or is DateTime2 not (fully) supported by SQLCLR ?

• I assume Row_Number doesn’t act only on rows of the window frame

  - by AspOnMyNet

  a) Quote is taken from http://www.postgresql.org/docs/current/static/tutorial-window.html for each row, there is a set of rows within its partition called its window frame. Many (but not all) window functions act only on the rows of the window frame, rather than of the whole partition. By default, if ORDER BY is supplied then the frame consists of all rows from the start of the partition up through the current row, plus any following rows that are equal to the current row according to the ORDER BY clause I assume Row_Number doesn’t act only on rows of the window frame, but instead always act on all rows of a partition? b) By default, if ORDER BY is supplied then the frame consists of all rows from the start of the partition up through the current row, plus any following rows that are equal to the current row according to the ORDER BY clause I assume that is only true for those window functions that act only on rows of the window frame ( thus above quote isn't true for ROW_NUMBER() function )? c) http://www.postgresql.org/docs/current/static/tutorial-window.html talks about PostgreSQL 8.4’s Windowing functions. Is everything in that article also true for Sql Server 2008’s Windowing functions thanx

• We have multiple app servers running against a single database. How do I ensure that each row in a q

  - by Dave

  We have about 7 app servers running .NET windows services that ping a single sql server 2005 queue table and fetch a fixed amount of records to process at fixed intervals. The amount of records to process and the amount of time between fetches are both configurable and are initially set to 100 and 30 seconds initially. Currently, my queue table has an int status column which can be either "Ready, Processing, Complete, Error". The proc that fetches the records has a sql transaction with the following code inside the transaction: 1) Fetch x number of records into temp table where the status is "Ready". The select uses a holdlock hint 2) Update the status on those records in the Queue table to "Processing" The .NET services do some processing that may take seconds or even minutes per record. Another proc is called per record that simply updates the status to "Complete". The update proc has no transaction as I'm leaning on the implicit transaction as part of the update clause here. I don't know the traffic exceptions for this but figure it will be under 10k records per day. Is this the best way to handle this scenario? If so, are there any details that I've left out, such as a hint here or there? Thanks! Dave

• Concatenate row values T-SQL

  - by Robert

  I am trying to pull together some data for a report and need to concatenate the row values of one of the tables. Here is the basic table structure: Reviews ReviewID ReviewDate Reviewers ReviewerID ReviewID UserID Users UserID FName LName This is a M:M relationship. Each Review can have many Reviewers; each User can be associated with many Reviews. Basically, all I want to see is Reviews.ReviewID, Reviews.ReviewDate, and a concatenated string of the FName's of all the associated Users for that Review (comma delimited). Instead of: ReviewID---ReviewDate---User 1----------12/1/2009----Bob 1----------12/1/2009----Joe 1----------12/1/2009----Frank 2----------12/9/2009----Sue 2----------12/9/2009----Alice Display this: ReviewID---ReviewDate----Users 1----------12/1/2009-----Bob, Joe, Frank 2----------12/9/2009-----Sue, Alice I have found this article describing some ways to do this, but most of these seem to only deal with one table, not multiple; unfortunately, my SQL-fu is not strong enough to adapt these to my circumstances. I am particularly interested in the example on that site which utilizes FOR XML PATH() as that looks the cleanest and most straight forward. SELECT p1.CategoryId, ( SELECT ProductName + ', ' FROM Northwind.dbo.Products p2 WHERE p2.CategoryId = p1.CategoryId ORDER BY ProductName FOR XML PATH('') ) AS Products FROM Northwind.dbo.Products p1 GROUP BY CategoryId; Can anyone give me a hand with this? Any help would be greatly appreciated!
